BELT REPLACEB.

Application filed June 8,

This invention relates to a novel device through the medium of which abelt may be easily and quickly replaced upon a revolving pulley withoutdanger to the operator.

The invention consists of the construction, combination and arrangemento-f parts hereinafter fully described and claimed, and illustrated inthe accompanying drawing, wherein:

Figure 1 is a view partly in elevation and partly in vertical sectionillustrating the manner in which'the device is adapted to be used inreplacing a belt on a revolving pulley,

Figure 2 is a view in side elevation of the upper portion of the device,and

Figure 3 is a sectiona view taken on the vertical plane indicated by theline 33 of Figure 2.

Corresponding and like parts are referred to in the followingdescription, and designated in the several views of the accompanyingdrawing, by similar reference characters.

The device comprises a handle or staff 1 which is preferably made ofwood and which shall be sufficiently long to permit a belt to bereplaced upon a revolving pulley from the floor. The upper end portionof the handle 1 is laterally enlarged, and such portion or head 2 isprovided with an opening 3 and is reenforced by a metal strap 4:. Theopening 3 is located centrally between the side edges of the head 2 andat a considerable distance below the top edge of the head. The strap 4is applied to the side and top edges of the head 2, and is secured inplace by pins 5 which pass through the head 2 above and below theopening 3. An axle 6, the diametrical dimension of which is greater thanits axial dimension, is fixed to the head 2, and is provided at itsinner side with a boss 7 and at its outer side with a radial flange 8.The boss 7 enters the opening 3, and projecting therefrom isa threadedstud 9 upon. which a retaining nut 10 is, mounted. A washer 11 ofgreater diameter than the corresponding dimension of the flange 8, ismounted upon the boss 7 between the head 2 and axle 6, and a washer 12is mounted upon the stud 9 between the head 2 and nut 10. A ring 13 isjournaled on the axle 6 between the flange 8 and washer 11, and isprovided at its outer side with an annular flange 14 which overliestheflange 8. The external. diameter of the ring 13 is similar to thecorresponding dimension of the washer 11, and the distance between theflange 1926. Serial No. 114,498.

8 and washer 11' is greater than the axial dimension ofthe ring so as topermit the axle 6 to be secured against casual movement on the head 2without causing any binding ac tion on the ring. The axle 6. washers 11and 12. nut 10 and ring 13 are made of metal.

The device is adapted to be used to replace a belt upon a revolvingpulley in the manner suggested in Figure 1, in which numeral 15designates a shaft, 16 a pulley carried by the shaft, and 17 a beltpartly applied to the pulley. To replace the belt 17 upon the pulley 16,the operator grasps the handle 1 at the desired distance from the ring13, places the ring in cont-act with' the lower face of the upper run ofthe belt at a point in close proximity to the pulley, lifts said run ofthe belt until it'is above the pulley, and thence moves the devicelaterally to carry the belt onto the pulley. As the head 2 ex tendsabove and below the ring 13, there is no danger of the belt 17 slippingoil of the ring, and there is no danger of carrying the ring intocontact with the spokes of the pulley 16, while moving the devicelaterally to effect the application of the belt to the pulley.

-It should be understood that the drawing is merely illustrative anddoes not pretend to give exact proportions. Furthermore, the saiddrawing is illustrative of a preferred construction, it being myexpectation that,

various changes and modifications may be made without departing from thespirit and scope of my invention.

'What is claimed -is: A belt replacer comprising a handle provided withan opening, an axle larger diametrically than axially and provided atits inner side with a boss entering the opening and a threaded studprojecting through the opening, a retaining nut mounted on they stud, aradially extending flange at the outer side of the axle, a washerpositioned between the handle and axle and extending radially beyond theflange, and a ring of equal diameter with the washer mounted upon theaxle between the flange and washer and provided with a flange overlyingthe first named flange, the axial dimension of the ring being less thanthe distance between the flange and washer to permit the axle to besecured tothe handle without exerting any binding action on the'ring.

In testimony whereof I affix my signature. HARRY C. KELLER.
